The invention provides a resin composition for laser engraving, having a binder polymer containing at least one of a structure unit represented by the following Formula (I) or a structure unit represented by the following Formula (II). In the Formulae, Q represents a partial structure which provides an acid group having an acid dissociation constant pKa of 0 to 20 when it is in the form of -Q-H; R1 to R3 each independently represent a hydrogen atom or a monovalent organic group; and A and B each independently represent a bivalent organic connecting group. The invention further provides a relief printing plate precursor having a relief forming layer containing the resin composition, a method for manufacturing a relief printing plate having crosslinking components of the relief forming layer and laser engraving the relief forming layer, and a relief printing plate formed thereby.
本发明提供了一种用于激光雕刻的树脂组合物,其粘结剂聚合物含有下式(I)所代表的结构单元或下式(II)所代表的结构单元中的至少一种。在式中,Q 代表部分结构,当它以-Q-H 的形式存在时,可提供酸解离常数 pKa 为 0 至 20 的酸基;R1 至 R3 各自独立地代表氢原子或一价有机基团;A 和 B 各自独立地代表二价有机连接基团。本发明进一步提供了一种浮雕印刷板前体,该前体具有含有树脂组合物的浮雕形成层;一种制造浮雕印刷板的方法,该方法具有交联浮雕形成层的组分和激光雕刻浮雕形成层;以及由此形成的浮雕印刷板。
